what kinda problems could i run in too? i have everything for the swap but the SC and i have been talking to a guy that has a GIII M90 with a 3.5 pulley.

Two things off the top of my head:

1) What are you going to do regarding tuning?

2) I would advise starting with a 3.8" (or even 4.0" or 4.2") until you get that tuned in, then start moving down pulley sizes.

EDIT: I'm confused...is this going onto the car in your sig?

yea it is going on the rivi, in my sig. we do have a tuner, and it can and will be tuned

Your Riv is already supercharged.

So, are you going to replace the L67 in your Riv with a L36 and top swap a supercharger on it? :?

What tuner works with a 95 GM PCM?

TunerCATs and TunerPro do..

From his posts on another forum, it looks like he'* going with a 97+ OBD2 swap.

I think this topic needs alot more details. Sketchy information is going to get a sketchy response.

my new engine is from a 1998 park ave its a L36 im doing a top swap with parts from a 1998 park ave ultra.

Why? What tuner? What trans? Details please.

why not just do a 96+ l67 if your already going to those lengths
